Um telefonema inesperado traz uma senhora idosa para sua casa de campo de infância, e memórias de um menino órfão que ela conheceu anos atrás vêm à tona.
It's school festival day and Min-hyuk is busy dancing and singing. However, it is not the stage but a toilet that binds his destiny. He is bewitched by a daring high school girl, Mi-hyun, who comes into the men's room because the women's room is full. From that day on, Min-hyuk woos her, escorts her home at night, stuffs her locker with roses, and clears passages for her in the morning after a snow fall. For all his efforts, he doesn't get much more than a tender glance from Mi-hyun. When she suddenly vanishes "sorry" are the only words she leaves behind.
